 ### Using SerialUPDI from platformIO
 It has been reported that, added to platformio.ini, the following works for making platformIO use SerialUPDI, but requires `python3` in the path. This is also a very aggressive configuration, and you may have better luck if you back off the speed to 115200 baud. UPDI does autobaud - you just want to make sure you pick a speed that the hardware will handle. 115200 works almost always, higher speeds are more demanding of how the UPDI circuit is wired up to meet required rise and fall times.
 
-However, note that this is probably obsolete and in most cases the same functionality can be achieved simply by setting `upload_protocol = serialupdi`, unless you have a specific reason to use this core's implementation.
